Description

L'invention concerne un élément de construction. L'invention concerne notamment, bien que non exclusivement, un plancher à poutrelles et à entrevous.The invention relates to a construction element. The invention relates in particular, although not exclusively, to a floor with joists and blocks.

L'invention concerne également un procédé de montage d'un tel élément de construction.The invention also relates to a method of mounting such a construction element.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION

Les planchers à poutrelles et entrevous sont bien connus du domaine de la construction. Ces planchers comprennent une pluralité de poutrelles, une pluralité d'entrevous de formes complexes emboîtés entre les poutrelles ainsi qu'une dalle de compression en béton qui a été coulée sur les poutrelles et les entrevous. La dalle de compression permet de reprendre les efforts en compression, les poutrelles n'étant pas suffisantes à cet égard. Lors du coulage de la dalle de compression et pendant toute la période de cure de ladite dalle de compression, de l'ordre d'une trentaine de jours, il est en outre nécessaire de soutenir le plancher à l'aide d'étais.Beam and interjoist floors are well known in the construction field. These floors comprise a plurality of beams, a plurality of interjoists of complex shapes nested between the beams and a concrete compression slab that has been poured on the beams and interjoists. The compression slab is used to absorb the compressive forces, since the beams are not sufficient in this regard. When the compression slab is poured and throughout the curing period of said compression slab, which is around thirty days, it is also necessary to support the floor using props.

Il s'avère donc relativement long et fastidieux de fabriquer le plancher à poutrelles et entrevous dans son intégralité. Un élément de construction et un procédé de montage sont connus de l'art antérieur US4885844 .It is therefore relatively long and tedious to manufacture the entire joist and interjoist floor. A construction element and an assembly method are known from the prior art. US4885844 .

OBJET DE L'INVENTIONSUBJECT OF THE INVENTION

Un but de l'invention est de proposer un élément de construction qui soit relativement plus simple et plus rapide à monter.An aim of the invention is to provide a construction element which is relatively simpler and quicker to assemble.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

En vue de la réalisation de ce but, on propose un élément de construction selon la revendication 1.In order to achieve this aim, a construction element according to claim 1 is provided.

Selon l'invention, chaque entrevous a une section transversale sensiblement rectangulaire de sorte que des coins opposés de chaque entrevous soient logés dans des coins correspondants des poutrelles, les poutrelles étant constituées d'un ou de deux profilés, l'élément de construction comportant en outre des moyens de liaison des poutrelles à une dalle de compression de l'élément de construction.According to the invention, each interjoist has a substantially rectangular cross-section such that opposite corners of each interjoist are housed in corresponding corners of the joists, the joists being consisting of one or two profiles, the construction element further comprising means for connecting the beams to a compression slab of the construction element.

Ainsi, il suffit simplement de poser les poutrelles et de venir faire reposer les entrevous entre lesdites poutrelles pour monter l'élément de construction. La forme des poutrelles et des entrevous permet un montage simple des entrevous entre les poutrelles.Thus, it is sufficient to simply lay the beams and to rest the blocks between said beams to assemble the construction element. The shape of the beams and blocks allows for simple assembly of the blocks between the beams.

L'élément de construction selon l'invention s'avère donc relativement simple et rapide à monter.The construction element according to the invention is therefore relatively simple and quick to assemble.

En outre, la coopération entre les poutrelles et les entrevous de section rectangulaire ainsi que la présence des moyens de liaison permettent que les poutrelles et les entrevous reprennent la majorité des efforts que l'élément de construction sera destiné à subir en plus de son poids propre.In addition, the cooperation between the beams and the rectangular section blocks as well as the presence of the connecting means allow the beams and the blocks to take up the majority of the forces that the construction element will be intended to undergo in addition to its own weight.

De plus, le montage de l'élément de construction selon l'invention peut être réalisé sans ou avec peu d'étais. Une fois les entrevous agencés entre les poutrelles, il est possible d'enchaîner directement sur le coulage d'une dalle de compression ou d'autres organes sur l'élément de construction selon l'invention.Furthermore, the assembly of the construction element according to the invention can be carried out without or with few props. Once the interjoists have been arranged between the beams, it is possible to directly continue with the casting of a compression slab or other members on the construction element according to the invention.

Dans la présente demande, par « plancher », on entend bien entendu l'ouvrage sur lequel un utilisateur est destiné à marcher et qui doit reprendre seul les efforts que l'ouvrage sera destiné à subir en plus de son poids propre.In this application, by "floor" we of course mean the structure on which a user is intended to walk and which must alone take up the forces that the structure will be intended to undergo in addition to its own weight.

Par « profilé », on entend pour la présente demande une pièce fabriquée pour s'étendre rectilignement selon un axe longitudinal et pour présenter un profil transversal déterminé en L, en T , en U, en H, en I, etc.For the purposes of this application, the term "profile" means a part manufactured to extend rectilinearly along a longitudinal axis and to have a specific transverse profile in the form of an L, T, U, H, I, etc.

Pour la présente demande, chaque poutrelle présente une section transversale comportant au moins deux coins qui définissent chacun soit une arête vive soit une arête arrondie formant congé.For the present application, each beam has a cross-section comprising at least two corners which each define either a sharp edge or a sharp edge. rounded forming a cone.

L'invention concerne également un procédé de montage d'un tel élément de construction qui comporte les étapes de :

  • agencer les poutrelles,
  • rapporter des moyens de liaison des poutrelles à une dalle de compression sur les poutrelles,
  • agencer les entrevous entre les poutrelles,
  • couler la dalle de compression de sorte à enrober lesdits moyens de liaison.
The invention also relates to a method of assembling such a construction element which comprises the steps of:
  • arrange the beams,
  • report means of connecting the beams to a compression slab on the beams,
  • arrange the blocks between the joists,
  • pour the compression slab so as to coat said connecting means.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 à 3, l'élément de construction selon le premier mode de réalisation de l'invention est ici un plancher 1. Le plancher 1 comporte ainsi une pluralité de poutrelles 2. De façon connue en soi, chaque poutrelle 2 repose ici au niveau de chacune de ses extrémités sur une poutre 3 (une seule poutre étant illustrée), les différentes poutrelles 2 s'étendant parallèlement les unes aux autres selon une direction longitudinale X.In reference to the Figures 1 to 3 , the construction element according to the first embodiment of the invention is here a floor 1. The floor 1 thus comprises a plurality of beams 2. In a manner known per se, each beam 2 here rests at each of its ends on a beam 3 (only one beam being illustrated), the different beams 2 extending parallel to each other in a longitudinal direction X.

Chaque poutrelle 2 est constituée ici de deux profilés 4 .Each beam 2 is here made up of two profiles 4.

Chaque profilé 4 s'étend rectilignement selon la direction longitudinal X et présente ici une section transversale en L. Chaque profilé 4 comporte ainsi une première aile 5a s'étendant parallèlement à la surface de la poutre 3 sur laquelle repose le profilé 4 et une deuxième aile 5b s'étendant perpendiculairement à la première aile 5a. Les deux ailes 5a, 5b sont ici identiques.Each profile 4 extends rectilinearly in the longitudinal direction X and here has an L-shaped cross section. Each profile 4 thus comprises a first wing 5a extending parallel to the surface of the beam 3 on which the profile 4 rests and a second wing 5b extending perpendicular to the first wing 5a. The two wings 5a, 5b are here identical.

Les profilés 4 sont donc accolés deux à deux pour constituer une poutrelle 2 de sorte que pour une même poutrelle 2 les deuxièmes ailes 5b des deux profilés 4 correspondants reposent l'une contre l'autre et les premières ailes 5a des deux profilés 4 correspondants s'étendent en direction opposée l'une à l'autre. Chaque poutrelle 2 formée par deux profilés 4 accolés a ainsi une section transversale générale en T inversé lorsque la poutrelle 2 est agencée entre les poutres 3.The profiles 4 are therefore joined two by two to form a beam 2 so that for the same beam 2 the second wings 5b of the two corresponding profiles 4 rest against each other and the first wings 5a of the two corresponding profiles 4 extend in opposite directions to each other. Each beam 2 formed by two joined profiles 4 thus has a general inverted T cross section when the beam 2 is arranged between the beams 3.

De préférence, les profilés 4, et donc les différentes poutrelles 2, sont en métal et en particulier en acier.Preferably, the profiles 4, and therefore the different beams 2, are made of metal and in particular steel.

De façon particulière, les profilés 4 des différentes poutrelles 2 du plancher 1 sont au moins solidarisés deux par deux par au moins un organe de connexion 7 appartenant au plancher 1.In particular, the profiles 4 of the different beams 2 of the floor 1 are at least joined two by two by at least one connection member 7 belonging on floor 1.

Plus précisément ici, le plancher 1 comporte plusieurs organes de connexion 7 qui sont chacun agencé pour solidariser tous les profilés 4, s'étendant entre les deux mêmes poutres 3 du plancher 1, entre eux. A cet effet, chaque organe de connexion 7 s'étend selon une direction transversale Y (soit une direction perpendiculaire à la direction X selon laquelle s'étendent les différents profilés 4), les organes de connexion 7 s'étendant donc parallèlement entre eux mais décalés l'un par rapport aux autres. Chaque organe de connexion 7 s'étend donc sensiblement parallèlement aux poutres 3. Chaque organe de connexion 7 s'étend par ailleurs sous les profilés 4 du plancher 1 de sorte à être en contact avec les premières ailes 5a des différents profilés 4. Chaque organe de connexion 7 est fixé à chacune desdites premières ailes 5a des différents profilés 4 de sorte que les différents profilés 4, s'étendant entre les deux mêmes poutres 3 du plancher 1, forment entre eux un tout-rigide de par l'organe de connexion 7.More specifically here, the floor 1 comprises several connection members 7 which are each arranged to secure all the profiles 4, extending between the same two beams 3 of the floor 1, to each other. For this purpose, each connection member 7 extends in a transverse direction Y (i.e. a direction perpendicular to the direction X in which the different profiles 4 extend), the connection members 7 therefore extending parallel to each other but offset from each other. Each connection member 7 therefore extends substantially parallel to the beams 3. Each connection member 7 also extends under the profiles 4 of the floor 1 so as to be in contact with the first wings 5a of the different profiles 4. Each connection member 7 is fixed to each of said first wings 5a of the different profiles 4 so that the different profiles 4, extending between the same two beams 3 of the floor 1, form a completely rigid whole between them by means of the connection member 7.

Ceci permet d'améliorer les caractéristiques mécaniques du plancher 1.This improves the mechanical characteristics of floor 1.

Chaque organe de connexion 7 est ici conformé en une bande rectiligne. La bande a ici une section rectangulaire. Chaque organe de connexion 7 est par exemple en métal et en particulier en fer. Chaque organe de connexion 7 est ici fixé aux différents profilés 4 par soudage.Each connection member 7 is here shaped into a rectilinear strip. The strip here has a rectangular section. Each connection member 7 is for example made of metal and in particular iron. Each connection member 7 is here fixed to the different profiles 4 by welding.

Le plancher 1 comporte en outre une pluralité d'entrevous 6 (dont une partie seulement est numérotée à la figure 1). Chaque entrevous 6 est agencé entre deux poutrelles 2 adjacentes, selon la direction transversale Y, du plancher 1 de sorte à reposer sur lesdites poutrelles 2.Floor 1 further comprises a plurality of joists 6 (only part of which is numbered at figure 1 ). Each interjoist 6 is arranged between two adjacent beams 2, in the transverse direction Y, of the floor 1 so as to rest on said beams 2.

Selon l'invention, chaque entrevous 6 a une section transversale rectangulaire. Chaque entrevous 6 est donc agencé entre deux poutrelles 2 de sorte que des coins opposés de chaque entrevous 6 soient logés dans des coins correspondants opposés des deux poutrelles 2 considérées.According to the invention, each interjoist 6 has a rectangular cross-section. Each interjoist 6 is therefore arranged between two beams 2 so that corners opposite of each joist 6 are housed in corresponding opposite corners of the two joists 2 considered.

De façon plus précise, chaque entrevous 6 est en appui sur les deux poutrelles 2 considérées de sorte que, selon la direction longitudinale X, une première arête de l'entrevous 6 s'étende sensiblement au niveau d'une arête correspondante de l'une des deux poutrelles 2, arête correspondante qui est définie comme étant la ligne de jonction entre les deux ailes 5a, 5b de l'un des profilés 4 associés à ladite poutrelle 2. En outre, chaque entrevous 6 est en appui sur les deux poutrelles 2 considérées de sorte que, selon la direction longitudinale X, une deuxième arête de l'entrevous 6, consécutive à la première arête de l'entrevous 6, s'étende sensiblement au niveau d'une arête correspondant de l'autre des deux poutrelles 2, arête correspondante qui est définie comme étant la ligne de jonction entre les deux ailes 5a, 5b de l'un des profilés 4 associés à ladite poutrelle 2.More precisely, each interjoist 6 rests on the two beams 2 considered so that, in the longitudinal direction X, a first edge of the interjoist 6 extends substantially at the level of a corresponding edge of one of the two beams 2, a corresponding edge which is defined as being the junction line between the two wings 5a, 5b of one of the profiles 4 associated with said beam 2. Furthermore, each interjoist 6 rests on the two beams 2 considered so that, in the longitudinal direction X, a second edge of the interjoist 6, consecutive to the first edge of the interjoist 6, extends substantially at the level of a corresponding edge of the other of the two beams 2, a corresponding edge which is defined as being the junction line between the two wings 5a, 5b of one of the profiles 4 associated with said beam 2.

Ainsi logé entre les deux poutrelles 2, l'entrevous 6 repose sur les premières ailes 5a desdites deux poutrelles 2 considérées et est encadré par les deuxièmes ailes 5b desdites deux poutrelles 2.Thus housed between the two beams 2, the interjoist 6 rests on the first wings 5a of said two beams 2 considered and is framed by the second wings 5b of said two beams 2.

Chaque entrevous 6 est ici une Brique de Terre Comprimée (encore appelée BTC).Each 6-joist here is a Compressed Earth Brick (also called BTC).

Chaque entrevous 6 a ici une section transversale de 29,5 centimètres de longueur Le par 9 centimètres de hauteur he, et une largeur le de 14 centimètres. Les entrevous 6 sont agencés de sorte que leurs faces longitudinales (définies comme ayant pour surface le produit de la longueur Le des briques par la largeur le des briques) s'étendent parallèlement aux premières ailes 5a des profilés 4.Each interjoist 6 here has a cross-section of 29.5 centimeters in length L e by 9 centimeters in height h e , and a width l e of 14 centimeters. The interjoists 6 are arranged so that their longitudinal faces (defined as having as their surface the product of the length L e of the bricks by the width l e of the bricks) extend parallel to the first wings 5a of the profiles 4.

Le plancher 1 comporte en outre une dalle de compression 8. De préférence, la dalle de compression 8 est en béton armé. La dalle de compression 8 a par exemple une épaisseur de 5 centimètres.The floor 1 further comprises a compression slab 8. Preferably, the compression slab 8 is made of reinforced concrete. The compression slab 8 has, for example, a thickness of 5 centimeters.

Selon l'invention, le plancher 1 comporte des moyens de liaison des poutrelles 2 avec la dalle de compression 8 du plancher 1.According to the invention, the floor 1 comprises means for connecting the beams 2 with the compression slab 8 of the floor 1.

Ceci permet encore davantage d'améliorer les caractéristiques mécaniques du plancher 1.This further improves the mechanical characteristics of floor 1.

A cet effet, les moyens de liaison comportent ici des cornières 9, qui s'étendent chacune à partir de l'une des poutrelles 2 jusque dans la dalle de compression 8. Chaque cornière 9 s'étend donc rectilignement selon la direction longitudinale X et présente une section transversale en L. Chaque cornière 9 est d'une longueur (longueur prise selon la direction longitudinale X) moins importante que celle des poutrelles 2.For this purpose, the connecting means here comprise angle irons 9, each of which extends from one of the beams 2 into the compression slab 8. Each angle iron 9 therefore extends rectilinearly in the longitudinal direction X and has an L-shaped cross-section. Each angle iron 9 is of a length (length taken in the longitudinal direction X) less than that of the beams 2.

Chaque cornière 9 comporte ainsi une première aile et une deuxième aile s'étendant perpendiculairement à la première aile. Les deux ailes sont ici identiques. Les deux ailes présentent une épaisseur moins importante que celle des ailes des profilés 4.Each angle iron 9 thus comprises a first wing and a second wing extending perpendicular to the first wing. The two wings are identical here. The two wings have a thickness less than that of the wings of the profiles 4.

Chaque cornière 9 est ici agencée au niveau de la poutrelle 2 associée de sorte à avoir sa premier aile s'étendant parallèlement à la deuxième aile 5b de l'un des profilés 4 de la poutrelle 2, dans le prolongement de ladite deuxième aile 5b, et de sorte à avoir sa deuxième aile s'étendant à l'intérieur de la dalle de compression 8 parallèlement aux premières ailes 5a des profilés 4 de la poutrelle 2.Each angle iron 9 is here arranged at the level of the associated beam 2 so as to have its first wing extending parallel to the second wing 5b of one of the profiles 4 of the beam 2, in the extension of said second wing 5b, and so as to have its second wing extending inside the compression slab 8 parallel to the first wings 5a of the profiles 4 of the beam 2.

De préférence, les cornières 9 sont agencées sur les différentes poutrelles 2 de sorte que le plancher 1 comporte entre 1 et 8 cornières par mètres carrés (m2) de plancher 1 et préférentiellement entre 3 et 6 cornières par m2 de plancher.Preferably, the angles 9 are arranged on the different beams 2 so that the floor 1 comprises between 1 and 8 angles per square meter ( m2 ) of floor 1 and preferably between 3 and 6 angles per m2 of floor.

De façon particulière, les cornières 9 sont agencées sur les différentes poutrelles 2 de sorte que pour quatre cornières 9 successives selon la direction transversale Y : les deux premières cornières 9 successives soient orientées de façon que leurs deuxièmes ailes s'étendent en direction l'une de l'autre et les deux deuxièmes cornières 9 successives soient orientées de façon que leurs deuxièmes ailes s'étendent en direction opposée l'une de l'autre. Alternativement, les cornières 9 sont agencées sur les différentes poutrelles 2 de sorte que toutes les cornières 9 soient orientées de façon que leurs deuxièmes ailes s'étendent toutes dans le même sens. Selon une autre option, les cornières 9 sont agencées sur les différentes poutrelles 2 de sorte que deux cornières 9 successives selon la direction transversale Y soient orientées de façon que leurs deuxièmes ailes s'étendent en direction l'une de l'autre. Selon encore une autre option, les cornières 9 sont agencées sur les différentes poutrelles 2 de sorte que deux cornières 9 successives selon la direction transversale Y soient orientées de façon que leurs deuxièmes ailes s'étendent en direction opposée l'une de l'autre.In particular, the angles 9 are arranged on the different beams 2 so that for four successive angles 9 in the transverse direction Y: the two successive first angles 9 are oriented so that their second wings extend in the direction of one another and the two successive second angles 9 are oriented so that their second wings extend in the opposite direction of one another. Alternatively, the angles 9 are arranged on the different beams 2 so that all the angles 9 are oriented so that their second wings all extend in the same direction. According to another option, the angles 9 are arranged on the different beams 2 so that two successive angles 9 in the transverse direction Y are oriented so that their second wings extend in the direction of one another. According to yet another option, the angles 9 are arranged on the different beams 2 so that two successive angles 9 in the transverse direction Y are oriented so that their second wings extend in the opposite direction to each other.

Les cornières 9 sont ici solidarisées à une poutrelle sur deux selon la direction transversale Y, l'autre poutrelle sur deux étant donc dépourvue de cornières 9.The angles 9 are here secured to one beam out of two in the transverse direction Y, the other beam out of two therefore being devoid of angles 9.

Chaque cornière 9 est ici soudée à la poutrelle 2 associée au niveau de sa première aile qui est en contact avec la deuxième aile 5b de l'un des profilés 4 de la poutrelle 2. Alternativement chaque cornière 9 peut être soudée aux deux profilés 4 de la même poutrelle 2.Each angle iron 9 is here welded to the associated beam 2 at the level of its first wing which is in contact with the second wing 5b of one of the profiles 4 of the beam 2. Alternatively, each angle iron 9 can be welded to the two profiles 4 of the same beam 2.

Au final, le plancher 1 a une épaisseur d'environ 16 centimètres ce qui est relativement peu important (un plancher poutrelles - entrevous de l'art antérieur pouvant présenter une épaisseur d'environ 30 centimètres).In the end, floor 1 has a thickness of approximately 16 centimeters, which is relatively unimportant (a prior art joist-joist floor can have a thickness of approximately 30 centimeters).

Le montage du plancher 1 selon le premier mode de réalisation de l'invention s'avère donc relativement simple et rapide.The assembly of the floor 1 according to the first embodiment of the invention therefore proves to be relatively simple and rapid.

En effet, il suffit dans un premier temps d'agencer les poutrelles 2 entre les poutres 3.In fact, it is sufficient to first arrange the beams 2 between the beams 3.

On agence ensuite des premiers entrevous 6 entre les poutrelles 2 au niveau des deux rives opposées du plancher 1 (c'est-à-dire au niveau des poutres 3). Ceci permet de s'assurer du bon espacement entre les poutrelles 2.The first joists 6 are then arranged between the beams 2 at the level of the two opposite edges of the floor 1 (i.e. at the level of the beams 3). This ensures the correct spacing between the beams 2.

Des étais de bords peuvent alors éventuellement être agencés au niveau des rives du plancher 1.Edge props can then possibly be arranged at the level of the edges of floor 1.

On vient ensuite rapporter les organes de connexion 7 sous les poutrelles 2 transversalement aux poutrelles 2, selon l'axe transversal Y, et souder les organes de connexion 7 aux poutrelles 2 pour solidariser les différents profilés 4 entre eux.The connection members 7 are then brought under the beams 2 transversely to the beams 2, along the transverse axis Y, and the connection members 7 are welded to the beams 2 to secure the different profiles 4 together.

On dispose alors les cornières 9 en les fixant aux poutrelles 2.The corners 9 are then arranged and fixed to the beams 2.

Puis, on pose le reste des entrevous 6 entre les poutrelles 2.Then, we place the rest of the 6 blocks between the 2 beams.

On vient alors poser un ferraillage avant de couler la dalle de compression 8 de sorte notamment à noyer dans le béton de la dalle de compression 8, les cornières 9 et ledit ferraillage.Reinforcement is then placed before pouring the compression slab 8 so as to embed the angles 9 and said reinforcement in the concrete of the compression slab 8.

Le plancher 1 ainsi décrit présente de nombreux avantages. En particulier, le plancher 1 est rapide et simple à monter. Aucun étai ou peu d'étais sont ainsi obligatoires pour la pose du plancher 1. Aucun important engin de levage n'est nécessaire.Floor 1 as described has many advantages. In particular, floor 1 is quick and easy to assemble. No props or few props are therefore required for laying floor 1. No major lifting equipment is required.

A portée identique, le plancher 1 a une masse propre peu importante relativement aux planchers à dalles pleines. Par ailleurs, le plancher 1 peut avoir une portée maximale plus importante que des planchers à poutrelles et entrevous de l'art antérieur.With the same span, floor 1 has a low self-mass relative to solid slab floors. Furthermore, floor 1 may have a greater maximum span than prior art joist and interjoist floors.

Le plancher 1 permet également d'avoir un gain de manutention et de transport. Le plancher 1 s'avère donc plus écologique. Le plancher 1 présente de plus une bonne isolation thermique et une bonne résistance mécanique.Floor 1 also allows for a gain in handling and transport. Floor 1 is therefore more ecological. Floor 1 also has good thermal insulation and good mechanical resistance.

En référence aux figures 4 et 5, l'élément de construction selon le deuxième mode de réalisation de l'invention va maintenant être décrit. L'élément de construction est ici également un plancher 101.In reference to the Figures 4 and 5 , the building element according to the second embodiment of the invention will now be described. The building element is here also a floor 101.

Chaque poutrelle 102 du plancher 101 est constituée ici d'un seul profilé 104.Each beam 102 of the floor 101 is here made up of a single profile 104.

Chaque profilé 104 s'étend rectilignement selon la direction longitudinale X et présente ici une section transversale en H couché ou encore en I. Chaque profilé 104 comporte ainsi une aile centrale s'étendant perpendiculairement à la surface des poutres 103 sur lesquelles le profilé 104 repose, une première aile secondaire s'étendant perpendiculairement à l'aile principale et reposant sur les poutres 103 et une deuxième aile secondaire s'étendant perpendiculairement à l'aile principale et à l'opposé de la première aile secondaire.Each profile 104 extends rectilinearly in the longitudinal direction X and here has a cross section in the shape of a lying H or even an I. Each profile 104 thus comprises a central wing extending perpendicular to the surface of the beams 103 on which the profile 104 rests, a first secondary wing extending perpendicular to the main wing and resting on the beams 103 and a second secondary wing extending perpendicular to the main wing and opposite the first secondary wing.

De préférence, les profilés 104, et donc les différentes poutrelles 102, sont en métal et en particulier en acier.Preferably, the profiles 104, and therefore the different beams 102, are made of metal and in particular steel.

Le plancher 101 comporte en outre une pluralité d'entrevous 106. Chaque entrevous 106 est agencé entre deux poutrelles 102 adjacentes selon la direction transversale Y de sorte à reposer sur lesdites poutrelles 102.The floor 101 further comprises a plurality of interjoists 106. Each interjoist 106 is arranged between two adjacent beams 102 in the transverse direction Y so as to rest on said beams 102.

Selon l'invention, chaque entrevous 106 a une section transversale rectangulaire. Chaque entrevous 106 est donc agencé entre deux poutrelles 102 de sorte que des coins opposés de chaque entrevous 106 soient logés dans des coins correspondants opposés des deux poutrelles 102 considérées.According to the invention, each interjoist 106 has a rectangular cross-section. Each interjoist 106 is therefore arranged between two beams 102 so that opposite corners of each interjoist 106 are housed in corresponding opposite corners of the two beams 102 considered.

De façon plus précise, chaque entrevous 106 est en appui sur les deux poutrelles 102 considérées de sorte que, selon la direction longitudinale X, une première arête de l'entrevous 106 s'étende sensiblement au niveau d'une arête correspondante de l'une des deux poutrelles 102, arête correspondante qui est définie comme étant la ligne de jonction entre la première aile secondaire et l'aile principale du profilé 104 de ladite poutrelle 102. En outre, chaque entrevous 106 est en appui sur les deux poutrelles 102 considérées de sorte que, selon la direction longitudinale X, une deuxième arête de l'entrevous 106, consécutive à la première arête de l'entrevous 106, s'étende sensiblement au niveau d'une arête correspondante de la même poutrelle 102, arête correspondante qui est définie comme étant la ligne de jonction entre la deuxième aile secondaire et l'aile principale.More precisely, each interjoist 106 rests on the two beams 102 considered so that, in the longitudinal direction X, a first edge of the interjoist 106 extends substantially at the level of a corresponding edge of one of the two beams 102, corresponding edge which is defined as being the junction line between the first secondary wing and the wing main section of the profile 104 of said beam 102. Furthermore, each interjoist 106 bears on the two beams 102 considered so that, in the longitudinal direction X, a second edge of the interjoist 106, consecutive to the first edge of the interjoist 106, extends substantially at the level of a corresponding edge of the same beam 102, corresponding edge which is defined as being the junction line between the second secondary wing and the main wing.

Par ailleurs, chaque entrevous 106 est en appui sur les deux poutrelles 102 considérées de sorte que selon la direction longitudinale X, une troisième arête de l'entrevous 106, consécutive à la première arête de l'entrevous 106, s'étende sensiblement au niveau d'une arête correspondante de l'autre des deux poutrelles 102, arête correspondante qui est définie comme étant la ligne de jonction entre la première aile secondaire et l'aile principale du profilé 104 de ladite poutrelle 102. En outre, chaque entrevous 106 est en appui sur les deux poutrelles 102 considérées de sorte que, selon la direction longitudinale X, une quatrième arête de l'entrevous 106, consécutive à la deuxième arête de l'entrevous 106 et à la troisième arête de l'entrevous 106, s'étende sensiblement au niveau d'une arête correspondant de la même poutrelle 102, arête correspondante qui est définie comme étant la ligne de jonction entre la deuxième aile secondaire et l'aile principale.Furthermore, each interjoist 106 bears on the two beams 102 considered so that, in the longitudinal direction X, a third edge of the interjoist 106, consecutive to the first edge of the interjoist 106, extends substantially at the level of a corresponding edge of the other of the two beams 102, corresponding edge which is defined as being the junction line between the first secondary wing and the main wing of the profile 104 of said beam 102. Furthermore, each interjoist 106 bears on the two beams 102 considered so that, in the longitudinal direction X, a fourth edge of the interjoist 106, consecutive to the second edge of the interjoist 106 and to the third edge of the interjoist 106, extends substantially at the level of a corresponding edge of the same beam 102, corresponding edge which is defined as being the junction line between the second secondary wing and the main wing.

Ainsi logé entre les deux poutrelles 102, l'entrevous 106 repose sur les premières ailes secondaires desdites deux poutrelles 102 considérées et est encadré des deuxièmes ailes secondaires et des ailes principales desdites deux poutrelles 102.Thus housed between the two beams 102, the interjoist 106 rests on the first secondary wings of said two beams 102 considered and is framed by the second secondary wings and the main wings of said two beams 102.

Chaque entrevous 106 est ici une Brique de Terre Comprimée (encore appelée BTC).Each 106 joist here is a Compressed Earth Brick (also called BTC).

Le plancher 101 comporte en outre une dalle de compression 108. De préférence, la dalle de compression 108 est en béton armé. La dalle de compression 108 a par exemple une épaisseur de 5 centimètres.Floor 101 also includes a slab of compression 108. Preferably, the compression slab 108 is made of reinforced concrete. The compression slab 108 has, for example, a thickness of 5 centimeters.

Selon l'invention, le plancher 101 comporte des moyens de liaison des poutrelles 102 à la dalle de compression 108 du plancher 101.According to the invention, the floor 101 comprises means for connecting the beams 102 to the compression slab 108 of the floor 101.

Ceci permet encore davantage d'améliorer les caractéristiques mécaniques du plancher 101.This further improves the mechanical characteristics of the 101 floor.

A cet effet, les moyens de liaison comportent ici des connecteurs 109 qui s'étendent chacun à partir de l'une des poutrelles 102 jusque dans la dalle de compression 108.For this purpose, the connecting means here comprise connectors 109 which each extend from one of the beams 102 into the compression slab 108.

Chaque connecteur 109 s'étend ici rectilignement selon la direction longitudinale X et présente une section transversale en U. Chaque connecteur 109 est d'une longueur (longueur prise selon la direction longitudinale X) moins importante que celle des poutrelles 102.Each connector 109 here extends rectilinearly in the longitudinal direction X and has a U-shaped cross-section. Each connector 109 is of a length (length taken in the longitudinal direction X) less than that of the beams 102.

Chaque connecteur 109 comporte ainsi une première aile s'étendant parallèlement à la deuxième aile secondaire du profilé 104 en reposant sur ladite deuxième aile secondaire du profilé 104, une deuxième aile s'étendant perpendiculaire à la première aile du connecteur 109 et une troisième aile s'étendant perpendiculairement à la deuxième aile du connecteur 109.Each connector 109 thus comprises a first wing extending parallel to the second secondary wing of the profile 104 while resting on said second secondary wing of the profile 104, a second wing extending perpendicular to the first wing of the connector 109 and a third wing extending perpendicular to the second wing of the connector 109.

De préférence, les connecteurs 109 sont agencées sur les différentes poutrelles 102 de sorte que le plancher 101 comporte entre 1 et 8 connecteurs par m2 de plancher 101 et préférentiellement entre 3 et 6 connecteurs par m2 de plancher 101.Preferably, the connectors 109 are arranged on the different beams 102 so that the floor 101 comprises between 1 and 8 connectors per m2 of floor 101 and preferably between 3 and 6 connectors per m2 of floor 101.

Chaque connecteur 109 est ici soudé à la poutrelle 102 associée au niveau de sa première aile qui est en contact avec la deuxième aile secondaire du profilé 104 de ladite poutrelle 102.Each connector 109 is here welded to the associated beam 102 at the level of its first wing which is in contact with the second secondary wing of the profile 104 of said beam 102.

Le montage du plancher 101 selon le deuxième mode de réalisation de l'invention s'avère donc également simple et rapide.The assembly of the floor 101 according to the second embodiment of the invention therefore also proves to be simple and rapid.

En effet, il suffit dans un premier temps d'agencer les poutrelles 102 entre les poutres 103.In fact, it is sufficient in the first instance to arrange the beams 102 between the beams 103.

On agence alors des premiers entrevous 106 entre les poutrelles 102 au niveau des deux rives opposées du plancher 101 (c'est-à-dire au niveau des poutres 103). Ceci permet de s'assurer du bon espacement entre les poutrelles.First blocks 106 are then arranged between the beams 102 at the level of the two opposite edges of the floor 101 (i.e. at the level of the beams 103). This makes it possible to ensure the correct spacing between the beams.

Des étais de bords peuvent alors éventuellement être agencés au niveau des rives du plancher 101.Edge props can then possibly be arranged at the level of the edges of floor 101.

On dispose alors les connecteurs 109 en les fixant aux poutrelles 102 de sorte à les agencer sur les parties supérieures des poutrelles 102.The connectors 109 are then arranged by fixing them to the beams 102 so as to arrange them on the upper parts of the beams 102.

Puis, on pose le reste des entrevous 106 entre les poutrelles 102.Then, we place the rest of the joists 106 between the beams 102.

On vient alors poser un ferraillage avant de couler la dalle de compression 108 de sorte notamment à noyer dans le béton de la dalle de compression 108, les connecteurs 109 et ledit ferraillage.Reinforcement is then placed before pouring the compression slab 108 so as in particular to embed the connectors 109 and said reinforcement in the concrete of the compression slab 108.

En référence aux figures 6 et 7, l'élément de construction selon le troisième mode de réalisation de l'invention va maintenant être décrit. L'élément de construction est également ici un plancher 201.In reference to the Figures 6 and 7 , the building element according to the third embodiment of the invention will now be described. The building element is also here a floor 201.

Chaque poutrelle 202 du plancher 201 est constituée ici d'un seul profilé 204.Each beam 202 of the floor 201 is here made up of a single profile 204.

Chaque profilé 204 s'étend rectilignement selon la direction longitudinale X et présente ici une section transversale en H couché ou encore en I. Chaque profilé 204 comporte ainsi une aile centrale s'étendant perpendiculairement à la surface des poutres 203 sur lesquelles le profilé 204 repose, une première aile secondaire s'étendant perpendiculairement à l'aile principale et reposant sur les poutres 203 et une deuxième aile secondaire s'étendant perpendiculairement à l'aile principale et à l'opposé de la première aile secondaire.Each profile 204 extends rectilinearly in the longitudinal direction X and here has a cross section in the shape of a lying H or even an I. Each profile 204 thus comprises a central wing extending perpendicular to the surface of the beams 203 on which the profile 204 rests, a first secondary wing extending perpendicular to the main wing and resting on the beams 203 and a second secondary wing extending perpendicular to the main wing and opposite the first secondary wing.

De préférence, les profilés 204, et donc les différentes poutrelles 202, sont en métal et en particulier en acier.Preferably, the profiles 204, and therefore the different beams 202, are made of metal and in particular steel.

Le plancher 201 comporte en outre une pluralité d'entrevous 206. Chaque entrevous 206 est agencé entre deux poutrelles 202 adjacentes selon la direction transversale Y de sorte à reposer sur lesdites poutrelles 202.The floor 201 further comprises a plurality of interjoists 206. Each interjoist 206 is arranged between two adjacent beams 202 in the transverse direction Y so as to rest on said beams 202.

Selon l'invention, chaque entrevous 206 a une section transversale rectangulaire. Chaque entrevous 206 est donc agencé entre deux poutrelles 202 de sorte que des coins opposés de chaque entrevous 206 soient logés dans des coins correspondants opposés des deux poutrelles 202 considérées.According to the invention, each interjoist 206 has a rectangular cross-section. Each interjoist 206 is therefore arranged between two beams 202 so that opposite corners of each interjoist 206 are housed in corresponding opposite corners of the two beams 202 considered.

De façon plus précise, chaque entrevous 206 est en appui sur les deux poutrelles 202 considérées de sorte que, selon la direction longitudinale X, une première arête de l'entrevous 206 s'étende sensiblement au niveau d'une arête correspondante de l'une des deux poutrelles 202, arête correspondante qui est définie comme étant la ligne de jonction entre la première aile secondaire et l'aile principale du profilé 204 ladite poutrelle 202. En outre, chaque entrevous 206 est en appui sur les deux poutrelles 202 considérées de sorte que, selon la direction longitudinale X, une deuxième arête de l'entrevous 206, consécutive à la première arête de l'entrevous 206, s'étende sensiblement au niveau d'une arête correspondante de la même poutrelle 202, arête correspondante qui est définie comme étant la ligne de jonction entre la deuxième aile secondaire et l'aile principale.More precisely, each interjoist 206 rests on the two beams 202 considered so that, in the longitudinal direction X, a first edge of the interjoist 206 extends substantially at the level of a corresponding edge of one of the two beams 202, a corresponding edge which is defined as being the junction line between the first secondary wing and the main wing of the profile 204 of said beam 202. Furthermore, each interjoist 206 rests on the two beams 202 considered so that, in the longitudinal direction X, a second edge of the interjoist 206, following the first edge of the interjoist 206, extends substantially at the level of a corresponding edge of the same beam 202, a corresponding edge which is defined as being the junction line between the second secondary wing and the main wing.

Par ailleurs, chaque entrevous 206 est en appui sur les deux poutrelles 202 considérées de sorte que selon la direction longitudinale X, une troisième arête de l'entrevous 206, consécutive à la première arête de l'entrevous 206, s'étende sensiblement au niveau d'une arête correspondante de l'autre des deux poutrelles 202, arête correspondante qui est définie comme étant la ligne de jonction entre la première aile secondaire et l'aile principale du profilé 204 de ladite poutrelle 202. En outre, chaque entrevous 206 est en appui sur les deux poutrelles 202 considérées de sorte que, selon la direction longitudinale X, une quatrième arête de l'entrevous 206, consécutive à la deuxième arête de l'entrevous 206 et à la troisième arête de l'entrevous 206, s'étende sensiblement au niveau d'une arête correspondant de la même poutrelle 202, arête correspondante qui est définie comme étant la ligne de jonction entre la deuxième aile secondaire et l'aile principale.Furthermore, each interjoist 206 rests on the two beams 202 considered so that in the longitudinal direction X, a third edge of the interjoist 206, consecutive to the first edge of the interjoist 206, extends substantially at the level of a corresponding edge of the other of the two beams 202, corresponding edge which is defined as being the junction line between the first secondary wing and the main wing of the profile 204 of said beam 202. furthermore, each interjoist 206 rests on the two beams 202 considered so that, in the longitudinal direction X, a fourth edge of the interjoist 206, consecutive to the second edge of the interjoist 206 and to the third edge of the interjoist 206, extends substantially at the level of a corresponding edge of the same beam 202, corresponding edge which is defined as being the junction line between the second secondary wing and the main wing.

Ainsi logé entre les deux poutrelles 202, l'entrevous 206 repose sur les premières ailes secondaires desdites deux poutrelles 202 considérées et est encadré des deuxièmes ailes secondaires et des ailes principales desdites deux poutrelles 202.Thus housed between the two beams 202, the interjoist 206 rests on the first secondary wings of said two beams 202 considered and is framed by the second secondary wings and the main wings of said two beams 202.

Chaque entrevous 206 est ici une Brique de Terre Comprimée (encore appelée BTC).Each 206 joist here is a Compressed Earth Brick (also called BTC).

Le plancher 201 comporte en outre une dalle de compression 208. De préférence, la dalle de compression 208 est en béton armé. La dalle de compression 208 a par exemple une épaisseur de 5 centimètres.The floor 201 further comprises a compression slab 208. Preferably, the compression slab 208 is made of reinforced concrete. The compression slab 208 has, for example, a thickness of 5 centimeters.

Selon l'invention, le plancher 201 comporte des moyens de liaison des poutrelles 202 à la dalle de compression 208 du plancher 201.According to the invention, the floor 201 comprises means for connecting the beams 202 to the compression slab 208 of the floor 201.

Ceci permet encore davantage d'améliorer les caractéristiques mécaniques du plancher 201.This further improves the mechanical characteristics of the 201 floor.

A cet effet, les moyens de liaison comportent ici des cornières 209, qui s'étendent chacune à partir de l'une des poutrelles 202 jusque dans la dalle de compression 208. Chaque cornière 209 s'étend donc rectilignement selon la direction longitudinale X et présente une section transversale en L. Chaque cornière 209 est d'une longueur (longueur prise selon la direction longitudinale X) moins importante que celle des poutrelles 202.For this purpose, the connecting means here comprise angle irons 209, each of which extends from one of the beams 202 into the compression slab 208. Each angle iron 209 therefore extends rectilinearly in the longitudinal direction X and has an L-shaped cross-section. Each angle iron 209 is of a length (length taken in the longitudinal direction X) less than that of the beams 202.

Chaque cornière 209 comporte ainsi une première aile et une deuxième aile s'étendant perpendiculairement à la première aile. Les deux ailes sont ici identiques. Les deux ailes présentent une épaisseur moins importante que celle des ailes des poutrelles 202.Each angle iron 209 thus comprises a first wing and a second wing extending perpendicular to the first wing. The two wings are identical here. The two wings have a thickness less than that of the wings of the beams 202.

Chaque cornière 209 est ici agencée au niveau de la poutrelle 202 associée de sorte à avoir sa première aile s'étendant parallèlement à l'aile principale de la poutrelle 202 et de sorte à avoir sa deuxième aile s'étendant à l'intérieur de la dalle de compression 208 parallèlement aux ailes secondaires de la poutrelle 202.Each angle iron 209 is here arranged at the level of the associated beam 202 so as to have its first wing extending parallel to the main wing of the beam 202 and so as to have its second wing extending inside the compression slab 208 parallel to the secondary wings of the beam 202.

De façon particulière, chaque cornière 209 est agencée sensiblement au centre de la poutrelle 202 associée.In particular, each angle iron 209 is arranged substantially in the center of the associated beam 202.

De façon particulière, les cornières 209 sont agencées sur les différentes poutrelles 202 de sorte que toutes les cornières 209 soient orientées de façon que leurs deuxièmes ailes s'étendent toutes dans le même sens. Alternativement, les cornières 209 sont agencées sur les différentes poutrelles 202 de sorte que pour quatre cornières 209 successives selon la direction transversale Y : les deux premières cornières 209 successives soient orientées de façon que leurs deuxièmes ailes s'étendent en direction l'une de l'autre et les deux deuxièmes cornières 209 successives soient orientées de façon que leurs deuxièmes ailes s'étendent en direction opposée l'une de l'autre. Selon une autre option, les cornières 209 sont agencées sur les différentes poutrelles 202 de sorte que deux cornières 209 successives selon la direction transversale Y soient orientées de façon que leurs deuxièmes ailes s'étendent en direction l'une de l'autre. Selon encore une autre option, les cornières 209 sont agencées sur les différentes poutrelles 202 de sorte que deux cornières 209 successives selon la direction transversale Y soient orientées de façon que leurs deuxièmes ailes s'étendent en direction opposée l'une de l'autre.In particular, the angles 209 are arranged on the different beams 202 so that all the angles 209 are oriented so that their second wings all extend in the same direction. Alternatively, the angles 209 are arranged on the different beams 202 so that for four successive angles 209 in the transverse direction Y: the first two successive angles 209 are oriented so that their second wings extend in the direction of one another and the two successive second angles 209 are oriented so that their second wings extend in the opposite direction of one another. According to another option, the angles 209 are arranged on the different beams 202 so that two successive angles 209 in the transverse direction Y are oriented so that their second wings extend in the direction of one another. According to yet another option, the angles 209 are arranged on the different beams 202 so that two successive angles 209 in the transverse direction Y are oriented so that their second wings extend in the opposite direction of one another.

De préférence, les cornières 209 sont agencées sur les différentes poutrelles 202 de sorte que le plancher 201 comporte entre 1 et 8 cornières par m2 de plancher 201 et préférentiellement entre 3 et 6 cornières par m2 de plancher 201.Preferably, the corners 209 are arranged on the different beams 202 so that the floor 201 comprises between 1 and 8 angles per m2 of floor 201 and preferably between 3 and 6 angles per m2 of floor 201.

Chaque cornière 209 est ici soudée à la poutrelle 202 associée au niveau de sa première aile qui est en contact avec la deuxième aile secondaire de la poutrelle 202.Each angle iron 209 is here welded to the associated beam 202 at the level of its first wing which is in contact with the second secondary wing of the beam 202.

Le montage du plancher 201 selon le troisième mode de réalisation de l'invention s'avère donc également simple et rapide.The assembly of the floor 201 according to the third embodiment of the invention therefore also proves to be simple and rapid.

En effet, il suffit dans un premier temps d'agencer les poutrelles 202 entre les poutres 203.In fact, it is sufficient in the first instance to arrange the beams 202 between the beams 203.

On agence alors des premiers entrevous 206 entre les poutrelles 202 au niveau des deux rives opposées du plancher 201 (c'est-à-dire au niveau des poutres 203). Ceci permet de s'assurer du bon espacement entre les poutrelles.The first blocks 206 are then arranged between the beams 202 at the level of the two opposite edges of the floor 201 (i.e. at the level of the beams 203). This makes it possible to ensure the correct spacing between the beams.

Des étais de bords peuvent alors éventuellement être agencés au niveau des rives du plancher 201.Edge props can then possibly be arranged at the level of the edges of floor 201.

On dispose alors les cornières 209 en les fixant aux poutrelles 202 de sorte à les agencer sur les parties supérieures des poutrelles 202.The corners 209 are then arranged by fixing them to the beams 202 so as to arrange them on the upper parts of the beams 202.

Puis, on pose le reste des entrevous 206 entre les poutrelles 202.Then, we place the rest of the 206 blocks between the 202 beams.

On vient alors poser un ferraillage avant de couler la dalle de compression 208 de sorte notamment à noyer dans le béton de la dalle de compression 208, les cornières 209 et ledit ferraillage.Reinforcement is then placed before pouring the compression slab 208 so as to embed the angles 209 and said reinforcement in the concrete of the compression slab 208.

Bien entendu l'invention n'est pas limitée aux modes de réalisation décrits et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiments described and variant embodiments can be made without departing from the scope of the invention as defined by the claims.

En particulier, bien qu'ici l'élément de construction soit un plancher, l'élément de construction pourra être différent et être par exemple un linteau, un escalier, un dallage, un dallage industriel, une rampe, un balcon, un plan de travail de cuisine ...In particular, although here the construction element is a floor, the construction element may be different and be for example a lintel, a staircase, a paving, an industrial paving, a ramp, a balcony, a kitchen worktop, etc.

Les profilés pourront avoir un autre profil que celui décrit à condition que la poutrelle ainsi formée comporte au moins deux coins pour que les entrevous puissent reposer dans lesdits coins des poutrelles. Les profilés pourront ainsi présenter, selon les normes européennes, une section transversale UAP ou en U. De façon générale, les poutrelles pourront être conformées, de par leur profilés, de sorte à présenter une section transversale en T, en H ... ou selon les normes européennes une section transversale IPE, HEA, HEB ...The profiles may have a profile other than that described provided that the beam thus formed has at least two corners so that the interjoists can rest in said corners of the beams. The profiles may thus have, according to European standards, a UAP or U-shaped cross-section. In general, the beams may be shaped, by their profiles, so as to have a T-shaped, H-shaped, etc. cross-section or, according to European standards, an IPE, HEA, HEB, etc. cross-section.

Les poutrelles, et donc les profilés, pourront être dans un tout autre matériau que le métal. Les poutrelles pourront ainsi être en matériau composite. Pour un même élément de construction selon l'invention, les poutrelles, et donc les profilés, pourront être en matériaux différents les uns des autres. Les poutrelles pourront tout aussi bien être en matériau brut ou bien être galvanisées ou encore être traitées contre la corrosion.The beams, and therefore the profiles, may be made of a material other than metal. The beams may therefore be made of composite material. For the same construction element according to the invention, the beams, and therefore the profiles, may be made of different materials from each other. The beams may just as well be made of raw material or be galvanized or even treated against corrosion.

Les poutrelles, et donc les profilés, pourront bien entendu avoir des dimensions différentes de celles décrites selon la portée désirée de l'élément de construction. Pour une section transversale en L d'un profilé, les deux ailes dudit profilé pourront par exemple avoir chacune une section transversale de 80 millimètres de largeur par 8 millimètres d'épaisseur, et une longueur de 4,50 mètres ou avoir chacune une section transversale de 100 millimètres de largeur par 10 millimètres d'épaisseur ou encore les deux ailes pourront avoir chacune une section transversale de 150 millimètres de largeur par 15 millimètres d'épaisseur. Pour une poutrelle ayant une section transversale IPE, la poutrelle pourra être conformée pour être de type IPE 220 qu'elle soit formée d'une ou de deux profilés. Pour une poutrelle ayant une section transversale HEA, la poutrelle pourra être conformée pour être de type HEA 120 ou encore HEA 140 qu'elle soit formée d'une ou de deux profilés.The beams, and therefore the profiles, may of course have dimensions different from those described depending on the desired span of the construction element. For an L-shaped cross-section of a profile, the two wings of said profile may for example each have a cross-section of 80 millimeters wide by 8 millimeters thick, and a length of 4.50 meters or each have a cross-section of 100 millimeters wide by 10 millimeters thick or the two wings may each have a cross-section of 150 millimeters wide by 15 millimeters thick. For a beam with an IPE cross-section, the beam may be shaped to be of type IPE 220 whether it is formed of one or two profiles. For a beam with an HEA cross-section, the beam may be shaped to be of type HEA 120 or HEA 140 whether it is formed of one or two profiles. two profiles.

Quelle que soit la forme de la section transversale des poutrelles, l'élément de construction pourra comporter un seul organe de connexion ou plusieurs organes de connexion. Quelle que soit la forme de la section transversale des poutrelles, chaque organe de connexion pourra solidariser seulement deux profilés (qu'il s'agisse des profilés formant une unique poutrelle ou de deux profilés formant des poutrelles différentes) ou pourra solidariser plus de deux profilés à la fois. Les organes de connexion pourront s'étendre transversalement aux poutrelles ou parallèlement aux poutrelles. Les organes de connexion pourront s'étendre sur les poutrelles et non sous les poutrelles. Les organes de connexion pourront permettre la solidarisation de profilés s'étendant parallèlement les uns aux autres ou dans le prolongement des uns des autres par exemple dans le cas d'un appui des poutrelles correspondantes sur l'une des poutres intermédiaires du plancher (par opposition aux poutres de rives).Regardless of the shape of the cross-section of the beams, the construction element may include a single connecting member or several connecting members. Regardless of the shape of the cross-section of the beams, each connecting member may connect only two profiles (whether the profiles forming a single beam or two profiles forming different beams) or may connect more than two profiles at a time. The connecting members may extend transversely to the beams or parallel to the beams. The connecting members may extend over the beams and not under the beams. The connecting members may allow the connection of profiles extending parallel to each other or in the extension of each other, for example in the case of support of the corresponding beams on one of the intermediate beams of the floor (as opposed to the edge beams).

L'élément de construction pourra alternativement ne comporter aucun organe de connexion.Alternatively, the construction element may not include any connection organ.

Les briques pourront également avoir des dimensions différentes de celles décrites.The bricks may also have different dimensions than those described.

Bien qu'ici les entrevous soient des BTC, les entrevous pourront être différents. Les entrevous pourront ainsi être des Briques de Terre Comprimées Stabilisées (encore appelée BTCS) ou encore des pré-dalles, par exemple des pré-dalles en béton armé. Différents types d'entrevous précités pourront être employés pour un même élément de construction selon l'invention.Although here the inter-joists are BTC, the inter-joists may be different. The inter-joists may thus be Stabilized Compressed Earth Bricks (also called BTCS) or even pre-slabs, for example reinforced concrete pre-slabs. Different types of inter-joists mentioned above may be used for the same construction element according to the invention.

On pourra également agencer les entrevous selon une autre orientation que celle présentée ici par exemple de sorte que la longueur des entrevous corresponde à la direction longitudinale des poutrelles au lieu que ce soit la largeur des entrevous qui corresponde à la direction longitudinale des poutrelles.The blocks can also be arranged in a different orientation than that shown here, for example, so that the length of the blocks corresponds to the longitudinal direction of the beams instead of the width of the blocks corresponding to the longitudinal direction. longitudinal of the beams.

Bien qu'ici les moyens de liaison comportent des connecteurs ou des cornières, les moyens de liaison pourront comporter tout autre élément de liaison pour lier poutrelles et dalle de compression tels que par exemple des goujons. Pour un même élément de construction, les moyens de liaison pourront bien entendu comprendre différents moyens différents comme par exemple des connecteurs en U au niveau des poutres sur lesquelles reposent les poutrelles et des cornières sur le reste de l'élément de construction.Although here the connecting means comprise connectors or angles, the connecting means may comprise any other connecting element for connecting beams and compression slab such as for example dowels. For the same construction element, the connecting means may of course comprise different different means such as for example U-shaped connectors at the beams on which the beams rest and angles on the rest of the construction element.

Pour une section transversale en L d'une cornière, les deux ailes de ladite cornière pourront par exemple avoir chacune une section transversale de 30 millimètres de largeur par 3 millimètres d'épaisseur. Pour une section en U d'un connecteur, le connecteur pourra être conformé pour être de type UPN 40. Une cornière et/ou un connecteur pourront avoir une longueur de 70 millimètres.For an L-shaped cross-section of an angle iron, the two wings of said angle iron may, for example, each have a cross-section of 30 millimeters wide by 3 millimeters thick. For a U-shaped section of a connector, the connector may be shaped to be of the UPN 40 type. An angle iron and/or a connector may have a length of 70 millimeters.
